France's King Henry II lined up to joust Gabriel, comte de Montgomery, seigneur de Lorges, a nobleman six years his junior, in the summer of 1559.

In their final pass, Montgomery's lance tilted up and splintered into two shards. One went through the king's visor and hit his eye, and the other lodged in his temple. Henry suffered for 10 days before dying in his bed.

Some reports say their shields displayed lion emblems, though disagreement exists. Sceptics also claim 'field of battle' in the quatrain probably shouldn't apply to the friendly jousting match that killed Henry II.

The French Revolution

In 1789, the French people decided they'd had enough of aristocratic rule. They revolted, storming the Bastille, a Paris fortress used as a prison. The fall of the Bastille, which symbolized the monarchy's abuses, marked the height of the French Revolution.

The peasants quickly took control of Paris and enforced their demands by kidnapping the royals. Some of them were even beheaded.

Napoleon's Conquest

'Pau, Nay, Loron, more fire than blood,Swimming in praise, the great man hurries to the confluence.

He will refuse entry to the magpies,Pampon and Durrance will confine them. '

What happened:

Pau, Nay, and Loron reference three towns in Paris, although the last is actually named Oloron. By using them, Nostradamus employed one of his favourite devices, the anagram.

Rearranging the cities' letters spells Napaulon Roy, which eerily resembles Napoleon the King in French.

'More of fire than of the blood' may refer to the non-noble lineage of Napoleon, who took power during a coup. 'Refuse entry to the magpies' could refer to Popes Pius VI and VII, both of whom Napoleon imprisoned.

Catholic King Philip II of Spain started ruling the country in 1556, and Spain became unbelievably wealthy for the first part of his reign. 'Seven' could be interpreted biblically, meaning 'a long time.'

His success, however, came to an unexpected halt in 1587 with the execution of Mary Queen of Scots, who was also Catholic. Her death effectively ended his alliance with England. A year later, he tried to invade England with his Spanish Armada fleet of ships, but England thwarted him.

The quatrain also hints at the Battle of Lepanto, where Spain slaughtered the fleet of the Ottoman Empire, an area to the South inhabited by many Arabs. Philip would later call for Muslim expulsion from Spain.

Lastly, the 'young onion' refers to 36-year-old Henri IV of France, a Huguenot and thus, Protestant. He and Philip disagreed on religion and battled until Henri's death.

Born in 1822, Louis Pasteur was a French chemist and microbiologist who discovered that the growth of micro-organisms causes fermentation. That discovery also proved bacteria doesn't simply appear spontaneously, as previously thought. Instead, it grows from already-living organisms in a process called biogenesis.

While Pasteur didn't first propose 'germ theory,' he convinced much of Europe of its validity. He invented a process for removing bacteria, 'pasteurization,' which is named after him. His early work also led to the creation of vaccines for rabies and anthrax.

However, in 1995, science historian Gerald L. Geison published a book showing Pasteur incorporated a rival's findings to make his anthrax vaccine functional. That finding partly 'dishonored' the great scientist, as Nostradamus predicted.

Hitler's Terror In Europe

'Beasts ferocious with hunger will cross the rivers,The greater part of the battlefield will be against Hister.Into a cage of iron will the great one be drawn,When the child of Germany observes nothing.'

What Happened:

Hitler -- who was born to poor parents in 1889 in Western Europe -- used his intense oratory skills to mobilize the Nazi party in Germany in the years following World War I. Germany, as a part of the Axis powers, also allied with Japan in the East. While many believe 'Hister' to be a typo, it's also an old name for the Danube River.

Hitler was born just miles from that river in what was then Austria-Hungary, also known as the 'Danube Monarchy.' Remember, Nostradamus often incorporated anagrams, such as 'Hister,' into his writing.

In August of 1945, the United States dropped two atomic bombs on the island nation of Japan, in Hiroshima and Nagasaki. Many historians argue the tragedy marked the end of World War II.

Those who escaped immediate detonation suffered painful radiation poisoning, and many died. A 'stone in the tree' in Nostradamus' quatrain could describe the shape of the mushroom cloud that engulfed the sky above the city. It could also mean a land-bound object, like a stone and a bomb, paradoxically appearing where it shouldn't -- a tree or the sky.

JFK's Assassination

John Kennedy's assassination in 1963 undoubtedly came from 'on high.' The bullet entered his head from roof-level.

The man accused of the crime, Lee Harvey Oswald, didn't live long enough to face trial. A Dallas nightclub owner killed him while in police custody. Oswald also persistently claimed he was a patsy, and therefore, innocent.

Even today, we don't know for sure who killed JFK. According to a recent Gallup poll, 61% of Americans believe it was a conspiracy.

Sept. 11, 2001

On the morning of Sept. 11, 2001, hijacked planes crashed into the Two Towers of the World Trade Center in New York City.

Scholars interpret forty-five degrees as either a reference to New York City's proximity to the 45th latitude or that the burning buildings would fall, creating a 45 degree angle to the ground -- even though they collapsed onto themselves.
